Rekha Gupta family income doubt

I was looking at Rekha Gupta information on MyNeta app. I noticed her husband's income. For many years his income was in range 5-8 lakh. But for last 5 year his income has increased exponentially. From 6 lac in 2020 to 97 lac in 2024. Do someone know what he do for living or is there something fishy.
